Why I DON'T Relay...
I and the American Cancer Society fundraising arm do not see eye to eye.
In short, they stole software I wrote to manage the fundraising for the Relay for Life of Second Life, with which they have raised hundreds of thousands of dollars (and continue to) and did so telling me that I was being "dismissed" for being too poor (!), claiming ownership over my work since I was a volunteer for them at the time, the funny thing about "work for hire" is that you actually have to give what is called consideration (not necessarily a wage) for the work to own it. I did not receive so much as a t-shirt or keychain.
Don't get me wrong, the ACS does a lot of good work, but their methods of funding that work leave much to desire.
